My mom called from Portland yesterday to relay this event. She feeds the
hummingbirds year-round and the feeders are near some large kitchen
windows. A hummer hit one of the windows and landed on a wood shelf that
sits just below it. The bird lay there motionless on its side. Then,
another hummingbird came and landed on the motionless hummingbird and
perched there a bit before flying away. Then it did the same thing a
second time! After it flew off again, my mom went out to see if the
hummer was dead, but it sat up and zoomed off.

My mother had the feeling it was the bird's mate. I couldn't tell her
one way or the other because I have never heard of such a thing. I
suppose Anna's could retain a pair bond through the winter if they
remain in one place all year. Does anyone have any guesses as to this
behavior?
